Figure 1 (A–D) Low-grade appendiceal mucinous neoplasm (LAMN). (A–C) Proliferation of mucinous epithelial cells forming villous structures within the appendiceal lumen. The underlying lymphoid tissue is atrophic, and the muscularis mucosae is effaced. Subepithelial fibrosis is present, and the lesion demonstrates a pushing (non-infiltrative) growth pattern. (D) The lesional epithelium shows abundant apical mucin and elongated nuclei with mild (low-grade) cytologic atypia. (H&E; magnifications: A ×40; B ×100; C ×200; D ×400).
